Need help, i'm a beginner

as i’m a beginner I wanted to make a script that counts results with user’s inputed numbers, using 2 formulas, but running this script makes it difficult to read the results, so I need help :

puts “formula (Vteor = 0.10472nrk)/it - lai atrastu atrumu m/s UN Vteor = 0.377nrk)/it - lai atrastu atrumu km/h”

puts “Ievadi savu rk (ritena kinematiskais radiuss)”
r = gets.chomp.to_f
puts "Ievadi savu it1 "
i1 = gets.chomp.to_f
puts "Ievadi savu it2 "
i2 = gets.chomp.to_f
puts “Ievadi savu it3”
i3 = gets.chomp.to_f
puts "Ievadi savu it4 "
i4 = gets.chomp.to_f
puts "Ievadi savu it5 "
i5 = gets.chomp.to_f
puts "Ievadi savu it6 "
i6 = gets.chomp.to_f

a = 0.10472.to_f #lai atrastu m/s
b = 0.377.to_f #lai atrastu km/h
w = 0.to_f #
s = 0.to_f #
  while w <= 7999 # 
  w += 500						
  s += 500

  	# 1p
res1 = awr/i1 # rezultats m/s
res11 = bwr/i1 # rezultats km/h
#2p
res2 = awr/i2 # rezultats m/s
res22 = bwr/i2 # rezultats km/h
#3p
res3 = awr/i3 # rezultats m/s
res33 = bwr/i3 # rezultats km/h
#4p
res4 = awr/i4 # rezultats m/s
res44 = bwr/i4 # rezultats km/h
#5p
res5 = awr/i5 # rezultats m/s
res55 = bwr/i5 # rezultats km/h
#6p
res6 = awr/i6 # rezultats m/s
res66 = bwr/i6 # rezultats km/h

puts “VteorI1 = #{sprintf(’%.5f’, res1)} M/S” + " VteorI1 = #{sprintf(’%.5f’, res11)} KM/h pie #{s} apgr/min" # sprintf%5f - 5 cipari pec komata (f - float, 5 - amount)

puts “VteorI2 = #{sprintf(’%.5f’, res2)} M/S” + " VteorI2 = #{sprintf(’%.5f’, res22)} KM/h pie #{s} apgr/min" #2p

puts “VteorI3 = #{sprintf(’%.5f’, res3)} M/S” + " VteorI3 = #{sprintf(’%.5f’, res33)} KM/h pie #{s} apgr/min" #3p

puts “VteorI4 = #{sprintf(’%.5f’, res4)} M/S” + " VteorI4 = #{sprintf(’%.5f’, res44)} KM/h pie #{s} apgr/min" #4p

puts “VteorI5 = #{sprintf(’%.5f’, res5)} M/S” + " VteorI5 = #{sprintf(’%.5f’, res55)} KM/h pie #{s} apgr/min" #5p

puts “VteorI6 = #{sprintf(’%.5f’, res6)} M/S” + " VteorI6 = #{sprintf(’%.5f’, res66)} KM/h pie #{s} apgr/min" #6p
  end

so when I run the script I see and inputing numbers it gives me the results :

VteorI1 = 2.24400 M/S VteorI1 = 8.07857 KM/h pie 500.0 apgr/min

but I need so the results would be :

Vteor1 ……… 500 apgr/min
Vteor1 ……… 1000 apgr/min
………
Vteor1 ………. 8000 apgr/min

Vteor2………… 500 apgr/min

Vteor2………… 1000 apgr/min

……………

Vteor2 ………… 8000apgr/min

etc.

I’m not sure to understand exactly what would want. But i think you need at less this functions:

>> 2.3465.round
=> 2
>> 2.3465.round(2)
=> 2.35
>> 2.3465.round(3)
=> 2.347

And if you need to put a line break in a string you must use a backlash with n
print “Hi\n”

If you got the answer then please share with me also. I have tried haml converter is it good to use or not.

ERB is faster and it easier to understand for someone doing HTML.

There’s no function in Ruby. Everything is a method. Whether Object method, any other class or module method, there’s no function. the round is a method on Float objects…
